Chemistry - Liquid Solution Question with Solution | TestHub

For glucose, sucrose, i = 1. For NaCl and$\mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{l}}_2$, the values of van't Hoff factor are 2 and 3 respectively.
${\text{ΔT}}_{\text{b}}\text{=}{\text{k}}_{\text{b}}\text{(im)}$
So effective$\mathrm{\Delta }{\mathrm{T}}_{\mathrm{f}}$for glucose, sucrose, NaCl and$\mathrm{C}\mathrm{a}\mathrm{C}{\mathrm{l}}_2$
$\propto \frac{1\times 10}{180},\frac{1\times 10}{342},\frac{2\times 10}{58.5}$and$\frac{3\times 10}{111}$
Thus, elevation in boiling point is maximum in case of$\mathrm{N}\mathrm{a}\mathrm{C}{\mathrm{l}}_{}$solution and hence,$\mathrm{N}\mathrm{a}\mathrm{C}{\mathrm{l}}_{}$would have maximum boiling point.
(Boiling point of solution = Boiling point of solvent$+\mathrm{\Delta }{\mathrm{T}}_{\mathrm{b}}$)
